Also called:
Gestational Trophoblastic Disease; Molar Pregnancy
Definitions related to hydatidiform mole:
-
A gestational trophoblastic disorder characterized by marked enlargement of the chorionic villi, hyperplasia of the villous trophoblastic cells and hydropic changes.NCI ThesaurusU.S. National Cancer Institute, 2021
-
A hydatidiform mole is a benign gestational trophoblastic disease developing during pregnancy. Resulting from an abnormal fertilization characterized by trophoblastic proliferation, normal embryo development is rendered impossible. Hydatidiform moles can be either complete or partial.OrphaNetINSERM, 2021
-
A placental disorder characterized by abnormal development with marked enlargement of the chorionic villi and hydropic changes which consist of hyperplasia of the villous trophoblastic cells.NICHD Pediatric TerminologyU.S. National Cancer Institute, 2021
-
A slow-growing tumor that develops from trophoblastic cells (cells that help an embryo attach to the uterus and help form the placenta) after fertilization of an egg by a sperm. A hydatidiform mole contains many cysts (sacs of fluid). It is usually benign (not cancer) but it may spread to nearby tissues (invasive mole). It may also become a malignant tumor called choriocarcinoma. Hydatidiform mole is the most common type of gestational trophoblastic tumor.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
Hydatidiform mole (HM) is an aberrant human pregnancy with absence of, or abnormal embryonic development, hydropic degeneration of chorionic villi, and excessive proliferation of the trophoblast.Human Phenotype Ontology (HPO)The Human Phenotype Ontology Project, 2021
-
Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A hydatidiform mole is growth of an abnormal fertilized egg or an overgrowth of tissue from the placenta. Women appear to be pregnant, but the uterus enlarges much more rapidly than in a normal pregnancy.Merck & Co., Inc., 2020
-
Gestational trophoblastic disease encompasses several disease processes that originate in the placenta. These include complete and partial moles, placental site trophoblastic tumors, choriocarcinomas, and invasive moles.WebMD, 2019
-
A molar pregnancy - also known as hydatidiform mole - is a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta.Mayo Foundation for Medical Education and Research
-
Molar pregnancy is a condition in which the placenta does not develop properly. The symptoms of molar pregnancy, which may include vaginal bleeding, severe morning sickness, stomach cramps, and high blood pressure, typically begin around the 10th week of pregnancy. Because the embryo does not form or is malformed in molar pregnancies,...National Center for Advancing Translational Sciences
-
Hydatidiform moles are chromosomally abnormal pregnancies that have the potential to become malignant (gestational trophoblastic neoplasia). Gestational trophoblastic disease includes tumors of fetal tissues, including hydatidiform moles, arising from placental trophoblasts. Syncytiotrophoblasts secrete human chorionic gonadotropin and,...Athenahealth, Inc., 2019
-
Hydatidiform mole, in human pregnancy, abnormal growth of the chorion, the outermost vascular membrane that in a normal pregnancy would enclose the embryo and ultimately give rise to the placenta. In the situation in which the hydatidiform mole develops, the embryo is usually either absent or...Encyclopedia Britannica, Inc., 2020
